The volume of an open cube carton is 5 cubic centimeters less than half of that of a cube whose edge length is 4cm. What is the surface area of the carton


The volume of open cube carton is: 4 × 4 × 4 △ 2-5 = 27 (CM) & 179;
The edge length of the open cube carton is: 179; √ 27 = 3 (CM)
The surface area of the uncovered cube carton is 5 × 3 × 3 = 45 cm and 178 cm;
A: the surface area of this carton is 45cm



A cube carton without cover, edge length 10 cm, calculate the surface area


"WQ Qihao":
There are only five sides of the carton
10²cm²×5=100cm²×5=500cm²
A total of 500 square centimeters of cardboard is required
Good luck and goodbye
